Epilepsy in children

Area of Science:

• Pediatric Neurology
• Epileptology

Background:

• Epilepsy affects 10.5 million children worldwide, presenting diverse clinical and etiological profiles.
• Significant advancements in syndrome-oriented diagnosis, EEG, and neuroimaging have enhanced understanding and management of childhood epilepsy over 15 years.

Purpose of the Study:

• To review the current understanding of childhood epilepsy, including its diversity, causes, and management strategies.
• To highlight the challenges in understanding age-related expression and mechanisms of epileptic encephalopathies.

Main Methods:

• Review of clinical and etiological diagnostic approaches, including EEG and neuroimaging.
• Analysis of recent therapeutic advancements and surgical options for pediatric epilepsy.

Main Results:

• Perinatal/postinfective encephalopathy, cortical dysplasia, and hippocampal sclerosis are key causes of severe symptomatic epilepsies.
• Ion channel defects contribute to both benign and severe epileptic encephalopathies, with underlying mechanisms for age-related expression remaining unclear.
• New antiepileptic drugs offer limited benefits, but improved drug selection and avoidance of polytherapy have enhanced quality of life.

Conclusions:

• While diagnostic tools have improved childhood epilepsy management, understanding of underlying mechanisms, particularly for epileptic encephalopathies, requires further research.
• Optimized drug selection and judicious use of epilepsy surgery are crucial for improving patient outcomes.
• Further investigation into the age-related expression of epilepsy and the origins of epileptic encephalopathies is warranted.
